To accomplish what you want, you should use FOSUserEvents::REGISTRATION_CONFIRM instead of FOSUserEvents::REGISTRATION_CONFIRMED.

You then have to rewrite rewrite your class RegistrationConfirmedListener like:

class RegistrationConfirmListener implements EventSubscriberInterface{    private $router;    public function __construct(UrlGeneratorInterface $router)    {        $this->router = $router;    }    /**     * {@inheritDoc}     */    public static function getSubscribedEvents()    {        return array(                FOSUserEvents::REGISTRATION_CONFIRM => 'onRegistrationConfirm'        );    }    public function onRegistrationConfirm(GetResponseUserEvent $event)    {        $url = $this->router->generate('rsWelcomeBundle_check_full_register');        $event->setResponse(new RedirectResponse($url));    }}

And your service.yml:

services:    rs_user.registration_complet:        class: rs\UserBundle\EventListener\RegistrationConfirmListener        arguments: [@router]        tags:            - { name: kernel.event_subscriber }

REGISTRATION_CONFIRM receives a FOS\UserBundle\Event\GetResponseUserEvent instance as you can see here: https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/FOSUserEvents.php

It allows you to modify the response that will be sent: https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Event/GetResponseUserEvent.php

"friendsofsymfony/user-bundle": "2.0.x-dev",

Not sure why the accepted answer works for you as REGISTRATION_CONFIRM happens after the token is confirmed.

In case you want to perform an action, redirect to another page with some additional form after the FOS registerAction I would suggest the following way.

This is the code that is performed on registerAction once the submitted form is valid by FOS:

FOS\UserBundle\Controller\RegistrationController

        if ($form->isValid()) {            $event = new FormEvent($form, $request);            $dispatcher->dispatch(FOSUserEvents::REGISTRATION_SUCCESS, $event);            $userManager->updateUser($user);            if (null === $response = $event->getResponse()) {                $url = $this->generateUrl('fos_user_registration_confirmed');                $response = new RedirectResponse($url);            }            $dispatcher->dispatch(FOSUserEvents::REGISTRATION_COMPLETED, new FilterUserResponseEvent($user, $request, $response));            return $response;        }

As you can see the first possible return happens after FOSUserEvents::REGISTRATION_SUCCESS event in case the response is null which in my case doesn't as I have configured a mailer to send a confirmation token and FOS is using an listener that listens to this FOSUserEvents::REGISTRATION_SUCCESS event and after sending an email it sets a redirect response.

FOS\UserBundle\EventListener\EmailConfirmationListener

/** * @return array */public static function getSubscribedEvents(){    return array(        FOSUserEvents::REGISTRATION_SUCCESS => 'onRegistrationSuccess',    );}/** * @param FormEvent $event */public function onRegistrationSuccess(FormEvent $event){    /** @var $user \FOS\UserBundle\Model\UserInterface */    $user = $event->getForm()->getData();    $user->setEnabled(false);    if (null === $user->getConfirmationToken()) {        $user->setConfirmationToken($this->tokenGenerator->generateToken());    }    $this->mailer->sendConfirmationEmailMessage($user);    $this->session->set('fos_user_send_confirmation_email/email', $user->getEmail());    $url = $this->router->generate('fos_user_registration_check_email');    $event->setResponse(new RedirectResponse($url));}

Okay I understand! So how do I redirect to another page?

I would suggest to overwrite checkEmailAction as most likely you don't want to overwrite the listener that sends an email as that's part of your workflow.

Simply:

TB\UserBundle\Controller\RegistrationController

/** * @return \Symfony\Component\HttpFoundation\Response */public function checkEmailAction(){    /** @var UserManager $userManager */    $userManager = $this->get('fos_user.user_manager');    /** @var string $email */    $email = $this->get('session')->get('fos_user_send_confirmation_email/email');    $user = $userManager->findUserByEmail($email);    return $this->redirect($this->generateUrl('wall', ['username' => $user->getUsername()]));}

As you can see instead of rendering FOS's check_email template I decided to redirect user to his new profile.

Docs how to overwrite an controller: https://symfony.com/doc/master/bundles/FOSUserBundle/overriding_controllers.html (basically define a parent for your bundle and create a file in the directory with the same name as FOS does.)

Route redirection can also be used:

fos_user_registration_confirmed:    path: /register/confirmed    defaults:        _controller: FrameworkBundle:Redirect:redirect        route: redirection_route        permanent: true
